时滞援助的两抑制性突触耦合的Chay神经元的同步

摘要

Synchronization in a pair of chaotic Chay neurons coupled by synaptically mutual inhibition is considered in this paper. It is shown that two coupled chaotic neurons with simple inhibition can synchronize out of phase when the coupling strength is above a certain critical value. At the same time, two chaotic neurons exhibit periodic bursting motions instead of the original chaotic ones.However, with the conduction delay being considered, in-phase bursting synchronization of two neurons can be enhanced under an efficient conduction delay. The size of windows, in which bursting synchronization is enhanced, increases with the coupling strength Hsyn. This result may be a guideline to understand collective motions in neurons.%一对抑制性突触耦合的混沌Chay神经元的同步模式被研究.结果表明当耦合强度超过临界值时,两抑制耦合的混沌Chay神经元能达到反相的同步.与此同时,两混沌的神经元变为周期而不是原来的混沌运动.然而,如果考虑耦合神经元信息的传导时滞,在有效的时滞下,两个耦合神经元的在相簇同步能增加.在相簇同步窗口的大小随着耦合强度的增加而增加.此结果对于我们理解神经元集群的运动是一个指导.
